according to my diagram, its pin 8 of S11(ecu).
This pin leads to the said light on dashboard of post Alfa code cars.For the likes of myself (pre code) we have to stick our own indicator light on.
Hope this helps?
my diagrams are dated 12/94.....Its got the wiring diagrams for the V6 version WITHOUT the Alfa Romeo code, and the V6 version with the Alfa Romeo code. I think all the wideboys have the code.
Have you got section 29A of the manual?
This chapter tells you all about the "code".
I asked the very same question in the previous postings re injector light, after having it replaced but no one replied. The ECU has to be disconnected for about 15mins to reset it, but someone on here lost the key memory after doing this so I'm a little reluctant to do it if there is another way.
